Electricity Free, wind powered Air Conditioning system from an old fridge

Has anyone ever thought of connecting a compressor from a refrigerator to a wind turbine and making an electricity free AC system for their house? It could be made from all free parts - turbine from barrel (vawt), dead fridge, etc. Please comment

I've thought of this before and put it on my list of things to do. Basically what you mean is to power the compressor with mechanical output of a wind turbine . I'm certain it can be done but it might be a bit of mucking around as you'd have to gear up the output to match the current electric motor speed to obtain similar performance.

Has anyone else had a go at this?

I'm not sure about retrofitting a refrigerator, but there is one major component that would have to be transitioned over, which is the compressor.

Most Air conditioners and Refrigerators work on the same concept which is transferring heat from one coil to another. There is an evaporation side and a compression side with a compressor and an expansion valve. If you change out the compressor to run on either directly from a wind turbine or indirectly, using a wind turbine to compress air, then you can run it without electricity.

Linux- in the book The Mosquito Coast, a crazy inventor (played by Harrison Ford in the film :P) invents an electricity-free fridge that runs on heat (ie uses a heat engine to run a compressor). I see no reason why this is impossible- I'd love to see the delicious irony and ultimate "green" achievement of a solar powered AC that doesn't use PV panels. Think like your idea, but powered with a Minto Wheel or something similar.

. Not only is it not impossible, gas-fired absorption A/C has been around for a while. My parents had an ArkLa-Servel unit at their house.
Yeah, propane/natural gas/kerosene fridges have been around for years. They used to be in heavy use in the Sout Pacific where consistent electricity was not an option.
Build it man, build it.
hmm i'm still going to have to harp on about the power of waterwheels, all people with rivers on their land whould be using them...

Well today I was researching how to set up a solar powered air conditioner. I have an old AC unit, I just need to find out how to hook that up to a solar panel.

I think the total output would be too low. A passive heating/cooling system may be a more viable solution... I'm not using AC this year - temp stays below 80, many days so far have been near 100. Still testing, but seems fine so far.
